FARNBOROUGH, England, July 18 (Reuters) - Airbus is not planning to respond with a new aircraft should U.S. rival Boeing go ahead with a proposed middle of the market jet, the European aerospace group’s chief executive said on Wednesday.

“We have no problem with the middle of the market because we are there,” Tom Enders told journalists at the Farnborough Airshow, saying Airbus could further improve its existing aircraft, such as the A321neo.

Reuters has reported that Airbus is looking at an extended-range version of the A321neo.

Enders was speaking after British budget carrier easyJet took its first A321neo to the airshow.

EasyJet CEO Johan Lundgren said, however, that the airline would not be interested in an XLR (extended range) version because it doesn’t fit with easyJet’s business model. (Reporting by Sarah Young and Victoria Bryan; Editing by Mark Potter)
